Time Card Calculator

For each day, subtract the clock in time from the clock out time to get the elapsed time, then subtract any unpaid break minutes to get hours worked. Add up every day to get the weekly total. If the weekly total goes over your overtime threshold, the hours above it are paid at the overtime multiplier. This calculator does all of that for you as you type, including the conversion to decimal hours and pay.

Work out the gap between clock in and clock out first, then take the break off. For example, 9:00 to 17:30 is 8 hours 30 minutes of elapsed time. Subtract a 30 minute unpaid lunch and you are left with 8 hours worked. Only unpaid breaks come off the total. Paid breaks stay in, so set the break field to 0 for those.

Divide the minutes by 60. So 15 minutes is 0.25 hours, 30 minutes is 0.5 hours, and 45 minutes is 0.75 hours. Decimal hours matter because payroll multiplies a decimal by the pay rate, not hours and minutes. Writing 8 hours 30 minutes as 8.5 makes the maths simple and stops the common mistake of multiplying the rate by 8.30.

Overtime is the time worked beyond a set threshold, paid at a higher multiplier. This calculator uses a weekly threshold, so once your total hours pass it, every hour above is multiplied by the overtime rate. With a 40 hour threshold and a 1.5 multiplier, working 45 hours pays 40 hours at the normal rate and 5 hours at one and a half times the rate.

Time and a half means each overtime hour is paid at 1.5 times the normal rate. If your rate is 30 per hour, time and a half is 45 per hour for overtime. It is the most common overtime rate, though some rules use double time (2 times) for holidays or hours worked beyond a second threshold. Set the multiplier field to match the rule that applies to you.

It handles it automatically. When the clock out time is earlier than the clock in time, the tool assumes the shift ran past midnight into the next day and adds 24 hours so the maths comes out right. A shift from 22:00 to 06:00 is correctly counted as 8 hours of elapsed time before breaks, rather than a negative number.

Weekly overtime kicks in once total hours for the week pass a threshold, commonly 40. Daily overtime kicks in once hours in a single day pass a threshold, often 8, no matter what the weekly total is. Some places use both rules at once. This calculator uses a weekly threshold, which suits most salaried and standard hourly setups. If your jurisdiction uses daily overtime, calculate each day against its own limit.

Rounding is optional and varies by employer. A common method is rounding to the nearest quarter hour using the 7 minute rule, where 1 to 7 minutes rounds down and 8 to 14 rounds up. Rounding must be applied evenly so it does not consistently favour the employer, which can break wage rules. If you are unsure, record exact clock times and let the totals fall where they land.

Multiply decimal hours by the pay rate. So 38 hours at 30 per hour is 1,140. If there is overtime, pay the regular hours at the normal rate and the overtime hours at the rate times the multiplier, then add the two together. This calculator separates regular pay and overtime pay so you can see exactly how the total is built up before it reaches a payslip.

A standard full time week is usually 40 hours, often five 8 hour days, though many countries and contracts use 35 to 38 hours. The standard week is what most weekly overtime thresholds are set to. Use the threshold field to match your own contract or local rule rather than assuming 40 applies everywhere.

Yes. Add a row for each working day across the period using the Add day button. Keep in mind that the overtime threshold in this tool is applied to the full set of rows as one total. If your overtime is assessed per week, run each week separately so the threshold is applied to seven days at a time rather than the whole fortnight.

Small gaps usually come from rounding, unpaid break handling, or how partial minutes are treated. Manual cards round to the nearest quarter hour while software often keeps exact minutes, so a few minutes a day can add up over a week. The fix is to agree on one method and apply it consistently. Tracked time from a timer removes the guesswork because the clock records the real start and stop.

Manual time cards are fine for a quick total or a single shift, which is exactly what this tool is for. For ongoing work across clients and projects they get error prone fast, because people fill them in from memory at the end of the week. Time tracking software records hours as they happen, applies rates automatically and turns the totals straight into invoices, which removes both the typing and the arguments.
